Abstract
A touch display panel and a manufacturing method thereof are provided. The touch display panel includes a substrate, a conductor, a first pressure sensing electrode and a second pressure sensing electrode. The conductor is stacked under the substrate, and the conductor is not connected to a bias. The first pressure sensing electrode is disposed on the substrate and disposed above the conductor. A compression zone exists between the first pressure sensing electrode and the conductor, so as to form a first pressure sensing capacitor. The second pressure sensing electrode is disposed on the substrate and disposed above the conductor. The compression zone exists between the second pressure sensing electrode and the conductor, so as to form a second pressure sensing capacitor connected in series with the first pressure sensing capacitor.
